An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42396 in the wild and no public exploit code.\n\nAffected product: PowerDNS Authoritative. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-42396/ (Markdown: https://insights.sbomify.com/CVE-2026-42396/index.md)","id":"CVE-2026-42396","markdown":"https://insights.sbomify.com/CVE-2026-42396/index.md","name":"CVE-2026-42396","record":{"aliases":["DEBIAN-CVE-2026-42396","GHSA-hm6h-mcgv-h2x8","UBUNTU-CVE-2026-42396"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerDNS Authoritative","requires_auth":"high_privilege","summary":"Attackers can cause catalog zone transfer failures in PowerDNS Authoritative by exploiting insufficient validation of member zone data.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[{"product":"authoritative","vendor":"powerdns"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Insufficient Validation of Member Zone Data May Cause Catalog Zone Transfer to Fail","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Insufficient Validation of Member Zone Data May Cause Catalog Zone Transfer to Fail","id":"CVE-2026-42396","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Allocation of Resources Without Limits or Throttling in Kibana Leading to Denial of Service","id":"CVE-2026-42397"},"packages":[],"prev":{"headline":"Denial of service in OX Dovecot CE","id":"CVE-2026-42395"},"products":["Authoritative"],"published":"2026-05-21","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-24698","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":8.1,"headline":"Race condition in n/a","id":"CVE-2020-24696","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-5470","kev_date_added":null,"published":"2015-11-02"},{"cvss_score":7.5,"headline":"Insufficient Validation of Autoprimary SOA Queries","id":"CVE-2026-42001","kev_date_added":null,"published":"2026-05-21"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-24697","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-5426","kev_date_added":null,"published":"2016-09-21"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-5427","kev_date_added":null,"published":"2016-09-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-21","vendors":["PowerDNS"]},"summary":"Attackers can cause catalog zone transfer failures in PowerDNS Authoritative by exploiting insufficient validation of member zone data.","url":"https://insights.sbomify.com/CVE-2026-42396/"}
